Metronome is one tool that we use when we are obliged to do the exercises. Tool to measure tempo constantly, shall we wear when we practice, whether practicing techniques, read music, rhythm or train. With the metronome, then our mastery of tempo will be more perfect, and can help develop a "sense of rhythmic" in counting beats, as well as games.
If we are practicing using a metronome, start with a slow tempo. Master the first part - the song that we train up to really - really memorized, and until we can play without mistakes. If it is true - perfectly true, raise the tempo gradually until it reaches the tempo that we really wanted.
For example, we want to play songs with the tempo of 120 bpm (bit per minute). If we have not mastered the tempo of 120, and can not play it right, then down the tempo. Choose a tempo that allows us to play without mistakes, for example we derive the tempo to 80 bpm, and then play it the song. If we can play without mistakes, raise the tempo to 90 bpm. Play again, and if we can do it without errors, then speed up the tempo, for example to 100 bpm. And so on, until we can reach the tempo of 120 bpm without making mistakes.
REMEMBER! Never once - once to raise or accelerate the tempo, if we still make mistakes, or are still not convinced with the tempo in which we live. By increasing the tempo gradually, in fact speed up our game to be perfect. Conversely, playing fast but many make a mistake; it will slow the process to perfection.
The advantage of using the tempo gradually is able to develop and strengthen the method - the method in terms of memorization, and strengthening techniques. Another advantage is that we played fair. When we play when we can not maintain a fixed tempo (tempo run), then we will immediately know and realize it.
Another way to practice with a metronome is to make the leap - a leap tempo. When the song that we play 120 bpm tempos, and we started practicing with the tempo of 80 bpm, we can do exercises like this:
Tempo 80 bpm: play without mistakes
Turn up the tempo to 120 bpm: try, maybe we made a mistake.
Lower to 90 bpm: play without mistakes
Turn up the tempo to 120 bpm: try again, might still make mistakes
Lower to 100 bpm: maybe we can play without mistakes
Turn up the tempo to 120 bpm: try again, maybe the error will be reduced
Lower to 100 bpm: maybe we can play without mistakes
Turn up the tempo to 120 bpm: try, we may already be expert.
The advantage of making the leap - a leap of pace, is able to accelerate the mastery of the game at the desired tempo. Practice by raising and lowering the tempo, it could be more productive, because we can control the muscles, fingering, and the techniques we use, because the technique on a fast tempo, different techniques in a slow tempo.
